2631626302

Overview

Fair-Rite 2631626302 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 31, providing an impedance of 115 ohms at 100 MHz. The component features an inner diameter of 10.16 mm and an outer diameter of 19.05 mm, with a length of 14.3 mm. It operates within a frequency range of 1 MHz to 300 MHz and supports temperatures from -55°C to +125°C.

Feature Summary

• Solid construction provides mechanical stability for free-hanging installation on cables.
• Material 31 composition ensures effective high-frequency noise attenuation in the 1-300 MHz range.
• Round geometry allows for uniform magnetic flux distribution around the conductor.

Applications

• Electromagnetic interference suppression on signal and power cables
• Common mode choke implementation for data lines
• Retroactive noise filtering on existing wire assemblies

Procurement Notes

Verify material composition and impedance specifications against current Fair-Rite datasheets before integration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure physical dimensions match the target cable bundle diameter to guarantee proper fit and magnetic coupling efficiency.

Selection Notes

Select this part when high impedance is required at lower frequencies compared to Material 43. Material 31 offers superior performance below 100 MHz. Verify that the 10.16 mm inner diameter accommodates the specific cable assembly. Consider thermal limits if operating near the maximum rated temperature.

Part Context

This component belongs to the Fair-Rite 26 series of round cable cores. These cores are widely used in industrial and commercial electronics for EMI mitigation. The 2631626302 variant specifically targets applications requiring robust noise reduction using nickel-zinc ferrite technology.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Alternative materials such as Fair-Rite 43 offer different impedance profiles but require re-evaluation of frequency response characteristics.
